Thermal Trips

GD Rectifiers offer a range of surface mount bimetallic thermal trips designed for protection of power semiconductors against overtemperature.

The bimetallic element of the thermal trip is made using two different pieces of metal bonded together, which is heated by the load current. The metals expand at different rates once they are heated which then causes the bimetallic element to bend which is used to trip the circuit breaker.

The range of thermal trips available range from 40-230°C and suit a large range of applications and mountings, heaters, cooling fans and heatsinks.
